As Twitchy reported, James O’Keefe has been teasing a new undercover video that looks to be about Democratic voter fraud, but O’Keefe and his company Project Veritas have been tight-lipped as to any specifics.

Andy Kroll of Mother Jones, however, thinks he has discovered a little bit more of what to expect from this mystery project:

James O’Keefe, the conservative provocateur, has been on the prowl in Colorado, the setting of a close Senate race between Democratic incumbent Mark Udall and GOP Rep. Cory Gardner, as well as a nip-and-tuck governor’s contest. Last week, O’Keefe and two of his collaborators tried to bait Democratic field staffers into approving voter fraud involving Colorado’s universal vote-by-mail program, according to three Democratic staffers who interacted with O’Keefe or his colleagues.

Democratic staffers in Colorado recently came to believe they were the subject of an O’Keefe operation after campaign workers became suspicious about would-be volunteers who had asked about filling out and submitting mail-in ballots for others. Recently, the 30-year-old O’Keefe has targeted the Senate campaigns ofArkansas Democrat Mark Pryor and Kentucky Democrat Alison Lundergan Grimes by filming undercover videos of staffers or the candidate.

And libs pounced on this little bit of reporting in an attempt to preemptively discredit whatever it is O’Keefe does finally release:

A hoot. James O'Keefe puts on a disguise mustache & goes undercover-but tweets out a pic of his undercover self. http://t.co/rzbF8lk9Bu
